3-MD Series Magnetic Drive Pump

Handling abrasive particulates and corrosive fluids in chemical processing can bring on numerous challenges. Little Giant's 3-MD Series is a proven answer to problems involving the circulation of mildly corrosive liquids and solutions. The 3-MD is constructed with durable materials, designed to deliver consistent performance to challenging industrial environments.

Features & Benefits

  • 1/20 hp open FC motor
  • Glass-filled polypropylene magnet housing
  • Glass-filled polypropylene volute
  • 1.1 specific gravity
  • Nitrile O-ring
  • Titanium thrust washers and shaft


Driven by a thermally protected, open, and fan-cooled motor, the 3-MD Series is constructed of a durable thermoplastic magnet housing and volute. The impeller is constructed of a glass-filled polypropylene and ceramagnet “A” (barium ferrite) for improved stability and rigidity. The 3-MD can tolerate high temperatures up to 150 °F (66 °C).
